ABSTRACT:
A fuel injection system with a fuel injection pump. The system comprises first correction means for correcting a first basic volume of fuel fed by the fuel injection pump using a correction value calculated so as to realize a predetermined constant engine speed during at least one predetermined engine operating condition, calculation mean for calculating the variation of the correction value corresponding to the fuel temperature at predetermined engine load in the predetermined engine operating condition, and determining means for determining at least one property of current fuel on the basis of the variation. Accordingly, the system can automatically detect the properties of a fuel while driving.
